CAR-COUPLING.

SPECIFIGATIONIorming part of Letters Patent No. 237,089, dated February1, 1881.

I Application filed October 23, 1880. (No model.)

To all whom it may concern:

Be it known that I, JAMES A. BURNS, of Sharpsburg", in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Oar-Couplings; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference markedthereon.

My invention relates to an improvement in car-couplings; and it consistsin making a car-coupling in two main parts, which, when duplicated, forma coupling for coupling together two cars, said two-parts of thecoupling, when duplicated, operating with relation to each other in themanner hereinafter described.

To enable others skilled in the art with which my invention is mostnearly connected to make and use it, I will proceed to describe itsconstruction and operation.

In the accompanying drawings, which form part of this specification,Figures 1 and 2 are top views or plans of the two main parts of myimprovement in car-couplings. Figs. 3 and 4. are perspective viewsof thesame. Figs. 5 and 6 are top views or plans of the two parts representedin Figs. 1, 2, 3, and 4 when said parts are pivoted together andduplicated for the purpose of coupling two cars together. Fig. 7 is atop view or plan of the duplicated parts when locked into each other,showing the relative position of said parts when two cars are coupledtogether.

The two main parts A and B may be constructed by the casting or forgingprocesses, and when made in the forms shown in Figs. 1, 2, 3, and 4 thepart A is pivoted in the part B, as indicated at J in Figs. 5, 6, and 7.The part B is furnished with recesses a b, and a pin-opening, c, for thereception of the ordinary coupling-pin, the opening 0 and recess b beingemployed for coupling with the ordinary coupling link and pin, the linkentering the recess-b, and the couplingpin entering the opening 0. Therecess a in the part B is for the reception of the part A. The shank Hof the part B is provided with the usual bolt I, for attaching the partB to the car or to the platform of the car. The part B is also furnishedwith a spring, 6, the forward end of which presses against theprojectionf of the part A, for holding the parts A in a locked conditionwith relation to parts 5 B when said parts are duplicated, as shown inFigs. 5, 6, and 7.

In Fig. 6 part of the shank A is broken away for the purpose of showingsaid spring and projection. To the limb d of the part A is attached achain, g, which maybe attached to any of the known hand-levers now usedin connection with brakes, for the purpose of manipulating them. Saidchain may be, if desired, attached to other parts of the part A, forexampleat h of the limb Z, or to the projection f. I leave the point ofattachment of the chain g and manner of its attachment to the hand-leverto the judgment of the mechanic.

Having the parts A and B constructed, united, and pivoted together, ashereinbefore described, and secured to the car or its platform, when theends of two cars are approaching for the purpose of being coupled theparts 7 5 A and B, thus duplicated, will be in relative position to eachother, as shown in Figs. 5 and 6, and when brought together will be inthe position shown in Fig. 7, the buffer-heads F F of the parts Bengaging with each other, and 8c the points a of the parts B engagingwith the recesses r of the limbs d of the parts A, thereby perfectly andsecurely coupling the cars together.

When the operator desires to uncouple the 8 cars he draws on the chaing, which will cause the limb Z to press on the limb d and the point 0 onthe side of the buffer-head F of the part B (of the duplicated parts)until the points It drop into the recesses m of the 0 limbs d, andthereby hold the parts A and B spread, as shown in Figs. 5 and 6, inwhich position the cars will be uncoupled.

Having thus described my improvement, what I claim as of my inventionis- 1. A car-coupling consisting of the parts A and B, constructedsubstantially as shown in the accompanying drawings, the part B having aspring, 0, which acts upon the part A, causing the two parts of thecoupling to I00 lock together, as shown in Fig. 7, in the ma11- nerherein specified, and for the purpose set forth.

2. A car-coupling composed of the parts A,

5 having the points h 0 and limbs d, with recesses m 1", and the parts Bconnected to said parts A, and having: huflcrhemls Fund point n, allconstructed and operating substantially in the manner as and for thepurpose herein shown and described.
